I had this printable hanging on our back door when we had a pool! (feel free to print it, too, if you’ve got a pool!)

It’s worked really well for my kids- I’ve found minimal wet, soggy towels littering the upstairs of the house, unlike the previous years. 🙂 And if they fight, they have to get out of the pool. The pool is a happy place. 🙂
